Influence of contact angle on droplet parameters in ellipsoidal wettability model Surf. Topogr.: Metrol. Prop. (IF 2.7) Pub Date : 2023-05-31 Zehua Xu, Yanbin Zhang, Xiaosen Wang, Kangshuai Li, Qiang He
Contact angle is one of the most important indexes to evaluate the hydrophobicity of solid surface. In order to explore the wetting characteristics of droplets on anisotropic solid surfaces, including contact angle, droplet radius, droplet height, contact radius, contact area and projected area, an ellipsoidal droplet contact angle model was established. Different from the ordinary plane ellipsoidal
